Itis obvious that the mutual interlocking of'all the members of the frog, in substantially the manner above set forth, produces a vmaximum of rigidity of the whole,l and that "each such overlap ing and interlocking connection between t e arts prevents displacefeatures of adjustability herein above re'- y.ferred to, but alsoimakes possible the ready replacement, Vwithout, removal or discarding 'of the entire fro of anyl part or parts that may be subjecte to the greatest wear. For instance, thel point of the frog may receive double the wear andtear that is received by either of the wing treads, because such point receives the shearing action of the wheel flange whichever flange -way such wheel flange traverses, while t e action upon either wing tread is `determined by the particular one of the intersecting tracks that is taken by the wheel, and therefore the point of the frog would require replacing twice as often as leither of thawing treads.- And again,`the

treads of the castings, forming the throat -of thefrog, are subjected to more `severe wear and shock, and require more frequent renewal, than do either of lthe wing rails. Still other advantages in construction 'and function may be found to inhere in the device.
